A scan driver capable of freely setting the width of emission control signals and of dividing the emission control signals at least twice in one frame to apply the emission control signals is disclosed. Embodiments of the scan driver include a shift register, receiving at least two start pulses in one frame to sequentially shift the start pulses in response to a clock signal and to thus generate at least two sampling pulses, and at least two signal generators for combining the at least two sampling pulses and at least two output enable signals with each other to supply scan signals to scan lines, and for combining the at least two sampling pulses output from the shift register with each other to supply at least two emission control signals to emission control signals lines in one frame. At least two emission control signals are supplied to emission control signal lines in one frame so that it is possible to change the brightness of the display without generating a flicker.
